Effective constant record of solution.
Fig. 4 shows the example of the operation of the processor 4 at DLN node according to the first embodiment.
Processor 4 receives one or more vehicle route request (steps 400) of Fig. 4.Processor 4 each receives
Vehicle route request calculate route solution, and via interface 8 with other DLN nodes sharing route solutions to establish
Consistent route solution (step 402) for vehicle route request.Processor 4 according to one be recorded in block chain or
Intelligent contract in multiple blocks calculates route solution, wherein the copy continuously updated is stored in local storage 6
In.Calculating can be used algorithm, such as dijkstra's algorithm, use figure vertex (such as the intersection about more vertex graphs
Point) and two vertex of the information of figure side (such as road between joint) to calculate figure between optimal route, wherein pushing up
Point is updated with one or more parameters at edge according to the variation of route solution consistent on such as block chain record.More
In advanced variation, the calculating of the route solution at DLN node 2, which is also contemplated, to be calculated/is total to identical about early stage
The information of the route solution calculated in the period by node 2 is enjoyed, the route solution not yet (and may be never)
Establish consistent route solution.The calculating of route solution is it is also conceivable to the other information being recorded in block chain, example
Such as, the information (figure edge) limited in relation to type of vehicle on certain roads.If the current block time, (block was built by last addition
Stand the time of the consistent route solution for the request of one or more vehicle routes) it is represented as t, and in time t
The state of block chain be represented as S (t), then the route solution for vehicle route request (affairs Tx) can be expressed
For function C (Tx, t+1)=(be to be approximately equal to?) C (Tx, S (t+1)), wherein S (t+1) includes S (t) and in node
Place calculates but not yet for the variation route solution unanimously tested.Different DLN nodes 2 can be identical vehicle
Route request (Tx) calculates different route solutions, because not every node 2 can be calculated/be shared identical
In period, and/or same group of vehicle route request is received and handled with identical sequence.Modal processor 4 is controlled via interface 8
Its route solution calculated is shared with other DLN nodes 2, for being recorded in next block of block chain as vehicle
Route request establishes consistent route solution.Modal processor 4 is in addition using the consistent road being recorded in current block
Line solution come calculate it is next calculate/in shared period new vehicle route request route solution.
According to another heuristic variation, the calculating of route solution also uses the output of random number generator, should be with
Machine number generator is initialised by the Hash output of newest block in seed such as block chain as additional input.If random number
The output of generator is indicated that then route solution can be expressed as the function of three parameters: Tx, S (t+1) and r by r.It is this
The heuristic effect of additional input is to be quickly obtained acceptable consistent route solution party in the case where not needing and excessively calculating
Case.Previously described technology is considered the heuristic technique of identical type, but when for given calculating/shared
Section, route solution are not present the dependence of stochastic inputs or constant in entire DLN.
In this first embodiment, each DLN node, which passes through, announces solution using the digital signature from DLN node
(according to bottom optimization algorithm calculate) come effectively be particular course solution vote.Ballot is determined by bottom optimization algorithm.
The optimization algorithm can have the parameter for causing not each node to find/calculate same routes solution.In detail below
The example of the operation according to the second embodiment at single distributed account book network node 2 and vehicle is described, but is retouched first
State the operation of system according to the second embodiment as a whole.
According to another second embodiment, the one of distributed account book network (DLN) is sent by vehicle route request first
A or multiple nodes 2, and then shared between node 2.It is then each reception instead of the processor 4 at each node 2
The vehicle route request arrived calculates independent route solution, and processor 4 is according to the one or more areas for being recorded in block chain
Pre-defined algorithm in block calculates a group route solution.Each group of route solution includes a set of route solution, and one
A each input affairs (vehicle route request) in the set for calculating/being received during shared period.Processor 4 via
The group route solution of its calculating is shared in the control of interface 8 with other DLN nodes 2, to be recorded in next block of block chain
In.Then the node 2 shared (as discussed in more detail below) of DLN is recorded in which of newest block group road about use
The ballot of line solution, for being recorded in next block of block chain.It is recorded in next block of block chain
Which group route solution ballot shows using as consistent group route solution.Processor at each DLN node 2
4 can be in identical calculations/calculate during the shared period and to share more than one group of route solution identical to be recorded in
In block.Multiple groups solution can be used for same group of vehicle route request (affairs) or for example for calculate/it is shared
The number of the vehicle request received at node during period increases, more and more to organize vehicle route request (affairs).
In this second embodiment, as described above, voting after all groups of solutions come forth.Ballot can be with base
In cost function, which is had based on different one or more parameters possible between node to measure each solution
It is mostly good.For example, one or more DLN node can be controlled by one or more shipping companies, and one or more other DLN
Node can be controlled by one or more city councils, and be used by these different nodes to measure the solution of the route of each announcement
The how well parameter of scheme can be very different.Route solution to publication can be configured as by the node that shipping company controls
One in scheme is voted, to minimize the total travel time of hand over of goods.On the other hand, the section controlled by city council
It puts one can be configured as in the route solution to publication to vote, to minimize the titanium dioxide in its city
Carbon emission amount (gram of the carbon dioxide of discharge).
Fig. 7 shows the propagation of the block chain according to the second embodiment.Each block is in nearest calculating/shared period
In record calculated group of solution, and the ballot for investing calculated group of solution is additionally recorded in directly in front
Block in.Equally, each block is linked to direct previous area by the output of the hash function of the content of previous block
Block, so that the consistent route solution for requesting block chain vehicle route provides the effective constant of consistent route solution
Record.
Fig. 6 shows the example of the operation according to the second embodiment at the processor of DLN node 2.
Processor 4 receives one or more vehicle route request (steps 600) of Fig. 6.Processor 4 is one group of received vehicle
Route request calculating group route solution, and via the control of interface 8 and 2 shared group route solution party of other DLN nodes
Case, to establish the consistent group route solution (step 602) of Fig. 6.According to the one or more blocks for being recorded in block chain
In one or more pre-defined algorithms complete a group calculating for route solution.If the current block time, (block was last
The time of the consistent route solution for vehicle route request is established in addition) it is represented as t, and the N number of affairs quilt of the group
Be expressed as Tx1, Tx2, Tx3......TxN, then organize route solution can be represented as function C=C (t+1, r, Tx1,
Tx2, Tx3...TxN), wherein r be can by with for the stochastic inputs generated in a manner of identical described in first embodiment.Node
Processor 4 can be directed to identical group of affairs (vehicle route request) or the affairs for different (such as biggish) group, in phase
Same calculating/continue the group route solutions calculated and shared one or more is other in the shared period.
It is recorded in by modal processor 4 and in calculated group of route solution of processor of other nodes 2
After in the new block of block chain, one of 4 selection group route solution of modal processor, and via interface 8 control about
Its information selected is shared with other DLN nodes, for being recorded in next block of block chain.Using in block
Record has the group route solution at most voted as consistent route solution in next block of chain；And vehicle
It is motivated to abide by consistent route solution, closes rule reward and/or application not for example, by formulating as discussed in detail below
